Grip Shift Cable Replacement

I am replacing the gear cable in my grip shifts, but when I took them apart a metal piece came out and I have no idea how to put it back, or how to wind the cable. Any ideas? I tried googling it and searching around, but to no avail. I'm currently trying to put the bike together, any advice would rock. Thanks!

The metal piece fits into a space on the stationary part of the shifter. Its little "mountain peak" is what generates the clicks as the rotary part of the shifter passes a notched thingie over the peak.

The cable winding isn't too bad. If you have the style of Gripshift I think you have, the cable will make a full clockwise loop (assuming a rear shifter), going up a ramp on the rotary section, and then exit through the curved guide that leads to the shift housing.

It's all crystal clear now, right?

Scroll down to page 8. This helped me put mine back together when I had no clue.

Maybe this Youtube video will help. It mentions the flat metal spring.

Thanks everyone. After fighting with it for over an hour, I've decided to improvise with thumbies I had laying around until I can find a pair of trigger shifters I like.

Oh come on. that's lame. There are two kinds of grip shift routings- ones where the cable end anchors in the [static] shell of the shifter and one where the cable end travels with the rotating grip. Figure out which one you have. The static end cable takes a figure-8 loop to get out of the shifter while the moving cable end is much more intuitive.

As far as the spring goes, there is a little "pocket' molded into the shifter body and the looped end is clockwise of the split end.

Of course you could always GENTLY disassemble the other side to take a look, but I'm guessing if that were possible we wouldn't be here.

I know, I know. But I don't want the grip shifters anyway. I frankenbiked the shifter for now:

Sounds like an MRX. To tell you the truth, a new replacement shifter, complete with new rubber grip and shift cable installed, doesn't cost all that much more than just the replacement cable.

&& isn't as aggravating to get back together, either.

I would go to your local bike coop or even just your LBS and buy a set of used take off 7 or 8 speed trigger shifters. SOOOO much nicer than grip shifters. Pretty much any bike that I buy, I immediately rip the grip shifters off, save the cables, and toss the shifters into the garbage and replace with trigger shifters.

You got the old style grip shifters, the newer ones are easier to install cables. For MTBiking, I like twist grip shifters better than the trigger. I like the trigger shifters for hybrids and such
